"""
|
|
Two examples illustrating modifications to SQLAlchemy's attribute management
|
|
system.
|
|
|
|
``listen_for_events.py`` illustrates the usage of
|
|
:class:`~sqlalchemy.orm.interfaces.AttributeExtension` to intercept attribute
|
|
events. It additionally illustrates a way to automatically attach these
|
|
listeners to all class attributes using a
|
|
:class:`.InstrumentationManager`.
|
|
|
|
``custom_management.py`` illustrates much deeper usage of
|
|
:class:`.InstrumentationManager` as well as
|
|
collection adaptation, to completely change the underlying method used to
|
|
store state on an object. This example was developed to illustrate
|
|
techniques which would be used by other third party object instrumentation
|
|
systems to interact with SQLAlchemy's event system and is only intended for
|
|
very intricate framework integrations.
